Existing Cellular Infrastructure Supports Millions of M2M Connections
The national 3G/4G carriers have made a huge investment in network expansion and technology improvements over the past few years with Verizon and ATT together spending over $13B in 2013 alone. These upgrades have enabled a myriad of new high-bandwidth internet services and devices including many cellular-based Machine-to-Machine (M2M) applications. In fact, there are now over 60M cellular M2M connections in the U.S. with this number expected to exceed 100M by 2016. Much of this investment by the carriers has taken place in rural and remote areas opening new possibilities and capabilities that did not previously exist.
PetroCloud Uniquely Offers a Cellular Based SCADA System as a Service
With its extensive hardware engineering and telemetry expertise, PetroCloud is uniquely able to leverage this expanded 3G/4G coverage in remote areas using its extended range RCU along with its strong national partnerships with both Verizon and ATT. PetroCloud is the only solution provider offering oil and gas SCADA as a Service to oil and gas operators nationwide as a Solution Partner with Verizon and a National Partner with ATT.
Modern SCADA Applications Require High Bandwidth and Low Latency
Traditional SCADA system design relies on low-bandwidth, proprietary radios that are expensive both in terms of CAPEX and OPEX. These legacy systems along with newer proprietary radios were never architected to support new, low-latency, high-bandwidth applications for the modern digital oilfield. Their limited capabilities are a function of their low bandwidth and when combined with the high total cost of ownership and their high latency, these systems are outdated before they are even deployed, and usually, oil and gas operators are responsible for maintaining these systems.
Cellular is Well-Suited for the Digital Oilfield
Many of the new SCADA radios are simply repackaged and re-priced developer kits that are resold with high margins. The marketing around these radios focuses on their increased range but fail to mention the low bandwidth and high latency which can range from several seconds to several minutes. Also overlooked is the fact that the world’s most prevalent, reliable radio infrastructure has already been built by the national carriers with cellular towers able to cover 1,200 sq. miles. Cellular technology is also better suited for automation in the digital oilfield with very low latency and extremely high bandwidth accommodating advanced monitoring of critical equipment along with HD video and cameras or 2 way automation and control of virtually any field device.
Comparison of PetroCloud SCADA as a Service to Traditional SCADA
PetroCloud is able to offer SCADA as a Service at a low monthly subscription rate using the PetroCloud Extended Range Cellular solution relying on existing national 3G/4G cellular networks with the high-bandwidth reliability, security, disaster recovery, and economies of scale inherent with the national carrier cellular infrastructure. Not only does PetroCloud provide traditional automation services in the oilfield, but the increased bandwidth enables new services that are not possible with a traditional SCADA system.
The table below compares traditional SCADA systems to PetroCloud SCADA as a Service:
|Proprietary Radios (traditional SCADA)||PetroCloud SCADA as a Service|

Cellular Based SCADA as a Service is the Future-Proof Solution
Traditional SCADA architecture and radio systems have simply not kept pace with cellular technology and modern, high-bandwidth, cloud-computing platforms enabling the Internet of Things (IoT) that have emerged recently. The low bandwidth and high latency of traditional SCADA system design limits true M2M two-way communication; whereas, the national cellular carriers have kept pace with this evolution by aggressively deploying 4G over the past several years enabling a revolution in true M2M applications with high-bandwidth, two-way control and monitoring. PetroCloud has leveraged both the high-bandwidth 4G network coverage and the leading-edge cloud-computing technologies to be at the forefront of a revolution in both M2M and cellular based SCADA system in offering oil and gas SCADA as a Service.
